Individual component diagnostics
From the diagnostics menu, you can run tests to check the status of various components in the MFP.
During many of the diagnostic tests, the MFP enters a special diagnostics mode, which allows you to
send print jobs and interact with the menus.
Paper-path-sensor test
1. Scroll to and touch Administration.
2. Touch Troubleshooting.
3. Touch Paper Path Sensors.
The paper-path-sensor test checks for the presence of media at each of the sensors along the paper
path. As the media passes each sensor, the sensor's state is updated. On the control-panel display,
each sensor is represented by a string of alphabetic letters followed by a corresponding status for
each sensor. Use the following table to associate the letters that are shown on the control-panel
display with the sensor that they represent. A “0” next to the letter indicates that no media is present.
A “1” indicates that media is present.
Table 6-4 Paper-path sensor letter designations
Letter Component Letter Component
A Tray 5 paper feed F PS103: top-of-page
B Tray 4 paper feed G
C Tray 3 paper feed H PS110: reversing paper sensor
D PS106: front paper width J PS108: exit sensor to the fuser
E PS102: tray 2 pre-feed K PS109: delivery
Manual sensor test
1. Scroll to and touch Administration.
2. Touch Troubleshooting.
3. Touch Manual Sensor Test.
The manual sensor test indicates the status of the sensors and switches in the MFP. On the control-
panel display, each sensor is represented by a string of letters followed by a corresponding status for
each sensor. Except for the paper-size switches, a “0” next to the letter indicates that no media is
present or the switch is open. A “1” indicates that media is present or the switch is closed. For the
paper-size switches (SW102), the number ranges from 0 to 7 to indicate the state of the three
switches. Use the following table to associate the letters that appear on the control-panel display with
the switch or sensor that they represent. Note that both uppercase and lowercase letters are used.
